COVID-19: Staying Cyber Secure

COVID-19 pandemic is changing our lives. People are concerned, and with that concern comes a desire for information, safety and support. Organized crime groups are exploiting the fear, uncertainty and doubt which COVID-19 brings to target individuals and businesses in a variety of ways.

The threat

Since mid-February, KPMG member firms have seen the rapid build-out of infrastructure by cybercriminals used to launch COVID-19 themed spear-phishing attacks and to lure targets to fake websites seeking to collect Office 365 credentials.

Not addressed to you by name but uses terms such as “Dear colleague,” “Dear friend” or “Dear customer”

Includes a veiled threat or a false sense of urgency

Directly solicits personal or financial information.

Of course if it sounds too good to be true, it probably is.

The response

There are some key steps you should take to reduce the risk to your organization and your employees, particularly as you move to remote working:

Raise awareness amongst your team warning them of the heightened risk of COVID-19 themed phishing attacks

Share definitive sources of advice on how to stay safe and provide regular communications on the approach your organization is taking to the COVID-19 pandemic

Make sure you set up strong passwords, and preferably two-factor authentication, for all remote access accounts; particularly for Office 365 access

Provide remote workers with straightforward guidance on how to use remote working solutions including how to make sure they remain secure and tips on the identification of phishing

Ensure that all provided laptops have up to date anti-virus and firewall software

Run a helpline or online chat line which they can easily access for advice or report any security concerns including potential phishing

Encrypt data at rest on laptops used for remote working given the risk of theft

Disable USB drives to avoid the risk of malware, offering employees an alternate way of transferring data such as a collaboration tool

Also, make sure that your finance processes require finance teams to confirm any requests for large payments during the COVID-19 pandemic. This confirmation can help to guard against the increased risk of business email compromise and CEO frauds. Ideally, use a different channel such as phoning or texting to confirm an email request.

Ensure that you apply critical security patches and update firewalls and anti-virus software across your IT estate, including any laptops in use for remote working. You should expect organized crime groups to exploit any failures in the maintenance of IT systems during this pandemic.

Make certain that you back up all critical systems and validate the integrity of backups, ideally arranging for off-line storage of backups regularly. Expect an increased risk of ransomware during the COVID-19 pandemic as organized crime groups exploit COVID-19 themed phishing.

Lastly, work with your incident and crisis management team to strive to ensure your organization has an alternate audio and video conferencing environment available. This alternate platform will be needed if you have a ransomware incident that disrupts your IT systems. And will also provide additional redundancy if your primary conferencing provider has capacity or availability issues.

COVID-19 will drive significant changes in how you and your organization work, stay safe and stay secure.
